Abstract

Ein Gleichspannungswandler hat einen Schalter (1), der durch ein periodisches Referenzsignal (Uref) zwischen einem offenen und einem geschlossenen Zustand umschaltbar ist. Durch das Tastverhältnis des Referenzsignals ist das Verhältnis.zwischen einer Eingangsspannung (Vcc) und einer Ausgangsspannung (Vout) des Gleichspannungswandlers festgelegt. Eine Referenzfrequenzquelle (6, 7, 8, 9) zum Liefern des Referenzsignals (Uref) umfasst eine Modulationsschaltung (6) zum Modulieren der Frequenz und/oder des Referenzsignals.
